3.6.1 Setting Mic Address (using Type 0 protocol)
The unit must be set to the correct Mic Address to allow
monitoring of communications between the mic and the router,
and also to identify the mic if the “Listen In” function is selected.
To set the Mic Address, determine the physical input that the
microphone is to be connected to, and enter the corresponding
value shown in Table 3.2.
The firmware within the microphone uses the Mic Address and
the Type 0 protocol to determine the correct “Channel Setting”.
Using the Type 0 protocol (compatible with BVR20 & BVR16M,
BVRD2M and CANBUS modules) the Mic Address and Channel
Setting may not be the same. This is shown in Table 3.2.
For example, if a microphone is connected to input 5 (BVRD2M)
or 9 (BVR20) then the Mic Address should be set to 5.
The Channel Setting would automatically default to 9.
